【摘要】 阐述了随着卫生监督信息系统需求的持续增长,从不同角度建立其需求模型时所存在的局限性。重点介绍了实施Zachman框架的信息系统需求工程建模方法的结果,包括实际信息系统顺应国家《卫生监督基本数据集标准》不断优化和完善的过程,以及当食品安全预警机制新需求产生时相应功能的平滑接入。实践证明,Zachman框架的使用,在杜绝系统需求分析歧义、隐性需求显性化和系统功能事件有序化方面,起到了很好的作用。更多还原

【Abstract】 After given a description about the sustained growth of health inspection information system requirements, and given a discussion about the limitations of building demand model from different viewpoints,this paper presents requirements engineering framework based on the Zachman Information Systems modeling methods.The Zachman demand model’ s outcomes include that health inspection information system can conform to the development and optimization of China Standard of Health Inspection and Supervision Dataset.The Zachman demand model’ s outcomes also include that new-requirements can be execute smoothly,such as food safety early warning problem.更多还原
